Strip or sand it? Which is more gooder?!?

Those things are about the best invention in the last hundred years. I use them for prep work on gasket surfaces. They'll strip an old intake gasket in about a minute flat. I've never tried them on a full panel, but I'd bet they'd do the trick in a hurry.

 

here ya go....

The ones I use are much larger (5"?) and not the Rol-Loc kind. Mine thread onto a regular 5/8" spindle of any body grinder or buffer. But they're made of the same stuff by the same company.

 

The 3M strip discs come with rol loc and solid. The solid ones can be used on grinders, start these things with a load, touching the metal, too many rpms and they will come apart, and they hurt. Did you ever work around guys who think any air tool with a trigger is like an accelerator pedal always reving it up. If they do it with these pads you better run. Work safe!

 

i helped a guy one time strip almost all the paint off a car with a razor blade, the kind you use to scrape stickers off glass, the car had a few layers of paint on it but the factory paint was still there, we just scraped it to there, didnt take long maybe an afternoon to do the whole car with two guys, no noise, no dust, he did sand after we were done and then primer/sealer and painted it, was a 64 valiant as i recall.

 

I was in an vo-tech auto body shop class, and happended to have a razor with a good soild holder in the trunk of the car.. Thought heck! the razor might work!? was working on a 64 Comet Cyclone at the time and aside from the scultping in the side of the car they have pretty flat panels. Started with the razor and in no time had a pile of paint on the floor (when it goes well in long runs, it sounds like velcro opening!) and a stripped trunk lid. The teacher came over asked me what the hell was I doing! So I showed him.. he just shook his head and walked away...

 

Does anyone make epoxy primer in a spray can? Where can you get it? What brand works the best? Will epoxy primer keep metal from rusting if the car is a daily driver or gets wet, etc.?

 

I've seen stuff advertised as epoxy in spray cans, but in my experience, nothing that comes in a can is very durable. It can't be since true epoxy cures when you add part A to part B, triggering a chemical reaction that cures the paint/primer. If they were true epoxies, they'd harden in the spray can.

 

Can't can epoxy... if it is real epoxy, it will need to have a catylist mixed in just prior to being sprayed in order to make it dry/harden...

Problem might be getting the catylist into the can...

 

9" variable speed with 60 or 80 grit. Will take you about a day and 20 disks to bare metal (at least that's what it took on my wagon). If it's inside, don't worry about primer right. Do the body work. If it's a damp climate, go with epoxy primer then do the body work. I personally prefer to do body work before epoxy primer because the epoxy is going to fill up your sandpaper quickly and make it useless.

Then 2k primer. then sealer.

Good luck...I hate sanding but it's so much better IMO than stripper (you gotta rough up the metal anyway with stripper besides all the cleaning and cleaning when you use it....and did I mention the MESS)

 

I just wanted to say a huge thanks to everybody for your help, there's no substitute for the voice of experience!

A special thanks to Scott Sullivan aka cheezwiz, I'm blown away you made time to give me advice. How freaking cool is that?!?

Thanks all!
